Note For input interrupts 0 to 3, 6 to 9 can also be used as the interrupt number.
C
Interrupt input Interrupt mask
Inputs to a CS1W-INT01 or CJ1W-INT01
Interrupt Input Unit (16 inputs/Unit)
Set to 0000 to FFFF hex
Bits 0 to 15 correspond to each interrupt task. Individual bit settings are as follows:
0: Enable (unmask) the interrupt.
1: Disable (mask) the interrupt.
Inputs to a C200HS-INT01 Interrupt Input
Unit (8 inputs/Unit)
Set to 0000 to 00FF hex
Bits 0 to 7 correspond to each interrupt task. Individual bit settings are as follows:
0: Enable (unmasks) the interrupt.
1: Disable (mask) the interrupt.
Inputs to a CJ1M-CPU2@ CPU Unit's Built-in
Inputs (4 inputs/Unit)
CJ2M CPU Unit inputs (when Pulse I/O
Module is mounted) (4 inputs/Block)
0000 hex: Enable (unmask) the interrupt (direct mode).
0001 hex: Disable (mask) the interrupt (direct mode).
0002 hex: Start decrementing counter and enable interrupt (counter mode).
0003 hex: Start incrementing counter and enable interrupt (counter mode).
N: Interrupt identifier
